Be Advised
High wind levels have the potential to suspend particulate matter into the air. High levels of PM10 may pose an impact to public health. It is recommended that active children and adults, and people with respiratory disease, such as asthma, limit their outdoor activities.

Potential increases in PM10 concentrations may increase to moderate or unhealthy level.

SYNOPSIS FROM THE PHOENIX OFFICE
Modest moisture return through southern and central Arizona will allow the development of isolated to scattered showers and thunderstorms today. This will especially be the case for higher terrain locations north and east of Phoenix. More predominant westerly flow will draw much drier air back into the region beginning Tuesday and continuing through the week. This will result in widespread dry weather though with temperatures staying near to slightly cooler than normal
